commit 5f62e044d3bd4f84378ce354898e8e21583ef169
Author: Richard Levitte <levitte at openssl.org>
Date:   Sun Sep 6 17:12:39 2015 +0200

    Fix enc so it properly treats BASE64 as text
    
    To set both the incoming and outgoing data when 'encrypting' or
    'decrypting' to FORMAT_BASE64 wasn't quite the right thing to do.
